Description:

Abstract:
The depth to bedrock map of Sauk County, Wisconsin, provides a general guide to the distribution and thickness of unlithified materials overlying the bedrock surface. In constructing this map, we considered areas of talus deposits, such as those along the shore of Devils Lake, to be unlithified material.
Locations of 1,337 Wisconsin Geological and Natural History Survey geologic logs (1912-2000) and Wisconsin Department of Natural Resources (WDNR) Well Constructor's Reports (WCRs; 1936-89) were plotted in a geographic information system. Locations of WCRs were verified using plat books, U.S. Geological Survey (USGS) 7.5-minute digital raster graphic maps (1996-97) and aerial photographs (1992).

Of the records used, 1,147 included a measurement of depth to bedrock. Wells that did not reach bedrock, according to WCRs, gave us minimum depth to bedrock for 190 locations in the county. For interpretive purposes, we estimated land-surface elevations and surface slope from a USGS digital elevation model with 30-meter resolution (2001). The Natural Resources Conservation Service (NRCS) Soil Survey Geographic (SSURGO) database of soils information (2000) provided us with additional data for areas of shallow bedrock.

We relied upon our interpretation of the geologic map of Sauk County (Clayton and Attig, 1990) to map the depth to bedrock in areas of the county where well records are sparse. The geologic map shows thick unlithified deposits (in the glaciated eastern part of the county and in areas of glacial lake deposits, outwash, windblown silt, and river valley alluvium) and shows bedrock where it is overlain by very thin, unlithified deposits. We used the WCRs to determine that the average depth to bedrock within units mapped by Clayton and Attig (1990) as bedrock having thin soil cover ranged from 16 to 21 ft. Therefore, in upland areas where well data are sparse, we mapped the depth to bedrock as less than 25 ft.

In the upland areas for which more well data were available, some WCRs indicated a depth to bedrock greater than 25 ft. We incorporated those data to depict local areas in the uplands where surficial deposits are thicker. We have also mapped an increase in depth to bedrock in the uplands where an area mapped as windblown silt by Clayton and Attig (1990) is coincident with an increase in the land-surface elevation. Although local increases in the depth to bedrock may also be found in upland areas where well records are not available, we have only mapped a thickening of deposits in the uplands where verified by drilling records or suggested by the presence of windblown deposits and topography.

In the valleys of the Driftless Area and in the glaciated part of Sauk County where geologic-log and well-construction data are sparse, we have inferred the depth to bedrock from the type of geologic material mapped (Clayton and Attig, 1990) and the topographic relief. For instance, in areas where the Johnstown moraine is present and where there is an increase in land-surface elevation, we have shown an increase in the depth to bedrock. Similarly, we have inferred an increase in the depth to bedrock where a local topographic high is coincident with an area mapped by Clayton and Attig (1990) as windblown deposits. We interpreted a decrease in the depth to bedrock where the topography suggests a modern stream has eroded surficial deposits.

Purpose:
This map was produced for the Sauk County Groundwater Project, a joint project of the Wisconsin Geological and Natural History Survey, the Sauk County Board of Supervisors, the Wisconsin Department of Natural Resources Bureau of Drinking Water and Groundwater, and the U.S. Geological Survey. The purpose of this project was to compile and analyze data regarding the county’s groundwater resources. Knowledge of the depth to bedrock is important to understanding the extent and thickness of surficial aquifers.

Attribute Accuracy:

Attribute Accuracy Report:
Values of the sk_d2b grid were checked by the authors on-screen and on proof plots and any errors were subsequently corrected. Using the GRIDSPOT7.0 Arc Macro Language (AML) macro (available at http://arcscripts.esri.com/details.asp?dbid=10959), the values of the sk_d2b grid were also checked against the source well data (sk_d2bwells) and rock outcrop locations in the NRCS SSURGO soils dataset to make certain that the source data were honored.
Logical Consistency Report:
The grid sk_d2b is a valid ArcInfo grid with a value table (sk_d2b.vat) and statistics table (sk_d2b.sta). The coverage sk_d2bwells has point topology.

Completeness Report: Visual inspection was performed to assure that all grid cells in sk_d2b within Sauk County had a depth to bedrock category value assigned.

Process Step:

Process Description:
1. The geologic unit polygons corresponding to bedrock units in Geology of Sauk County, Wisconsin (digital information) were selected, and wells of sk_d2bwells located within those bedrock polygons were selected. For these wells, it was determined that the average depth to bedrock was 20 feet.

2. In the areas of the bedrock polygons, bedrock elevation contours (contour interval = 50 feet) were created that were 20 feet below the land surface indicated by the NED.

3. Contours were added in the areas of unlithified material indicated by Geology of Sauk County, Wisconsin (digital information), controlled by the well information in sk_d2bwells. The contours were then edited to match the well data in all areas.

4. The contours and point bedrock elevations at wells were interpolated to an ArcInfo grid using the ArcInfo TOPOGRID command. The resulting grid was set to the land surface elevation of the NED in very small areas where the interpolation set the bedrock elevation above the land surface, and that grid was checked against the well data using the ArcInfo LATTICESPOT command. The contours were subsequently edited to remove any errors, and this step was repeated until the authors were satisfied with the results. Contours at a much smaller interval (down to 5 feet) were added in areas of steep bedrock topography, e.g., steep slopes in the Driftless Area.

5. The final bedrock elevation grid was subtracted from the NED in the Grid module of ArcInfo, with the resulting grid being an approximate grid of depth to bedrock. This grid was reclassified into zones of depth to bedrock. These zones were further edited on-screen by the authors based on the geologic map (sk_geol), well data (sk_d2bwells), and the NRCS SSURGO rock outcrop locations (SSURGO). The GRIDSPOT70 AML was used to check that the value of the sk_d2b grid honored the depth to bedrock measurements at each well and SSURGO rock outcrop location.
